Abstract
We have developed a super-high-speed elevator considered to be the fastest in the world. However, the vibration of elevator cars increases in proportion to the traveling speed ; It is therefor necessary to develop new vibration suppression methods for comfort in riding. First, we developed oil damper for roller guides which can change damping coefficient easily. Second, we developed the vibration control mechanism proposed in our former report. Lastly, the car vibration test equipment system of the real size was developed for verifying these suppression methods. The results of experiments indicate that the oil damper has a high damping effect. It can suppress car vibration effectively. Furthermore, the car vibration control mechanism could suppress vibration to half of the uncontrolled case. We also investigated problems which occurred when we applied this mechanism to super-high-speed elevators.
